Title: Treating machine parts having rolling surfaces
IPC: C23C16/02
Filed: 1954-11-16
Abstract: 769,467. Coating with hard titanium compounds. METALLGES. AKT.-GES. Nov. 16, 1954 [Nov. 16, 1953; Nov. 25, 1953], No. 33198/54. Class 82(2) The resistance to wear of machine parts having rolling surfaces, such as ball or roller bearings and gear wheels, is improved by depositing, by a gas-phase reaction, on at least one of the surfaces taking part in the rolling, a coating consisting of a hard nitride, boride and/or silicide'of titanium. A hard titanium carbide may be additionally deposited on the surface. Nitride coatings may be deposited from mixtures of titanium tetrachloride, hydrogen and nitrogen, silicide coatings may be formed by first depositing titanium from titanium tetrabromide and hydrogen and then converting this to silicide by treatment with a mixture of silicon tetrachloride and hydrogen, and boride coatings may be formed in an analogous manner to that for silicides except that boron trichloride instead of silicon tetrachloride is added to the hydrogen in the last stage. A heterogeneous coating compound of a layer of nitride and a layer of carbide may be obtianed by first depositing a coating of nitride and then depositing thereover a layer of carbide from a mixture of titanium tetrachloride, hydrogen and hydrocarbons suchas methane. Rolling surfaces of steel and bronze are refered to. Reference has been directed by the Comptroller to Specification 731,990.

Abstract: 466,789. Controlling change speed gearing and motors. HERBERT, Ltd., A., and LLOYD, A. H. Dec. 4, 1935, No. 33594. [Class 80 (ii)] [Also in Group XXII] In a variable-speed driving means, different speeds are obtained partly by gearing and partly by an electric motor, the change-speed gearing being preselective with selector and main controls and the variable-speed driving motor being operable from the same controls. The motor, which may be either A.C. with a pole-change device or a resistance-controlled D.C. motor, drives through a four-speed gear, operated by sliding collars 22, 31, Fig. 3, controlling friction clutches, the spindle 35. Slidable yokes 23, 32, engage the clutch collars and these are moved by the engagement of their stems 24, 33 with selected projections on the " preselector " members 43. The latter are adjusted while one gear train is operating by a handle 49, Fig. 4 ; subsequent rotation of a handle 58 closes the members 43 and thus moves the clutch-actuating stems. A further stem 42, Fig. 3, extends within the operating path of the " preselector " and this is moved to control the speeds of the motor through a switch-rod 38. Reversal of the motor is effected by a separate control lever. A two-speed motor is used in the above embodiment to give eight speed changes but other combinations of motor and gear speeds may be employed. Specifications 382,784, 429,741, 434,393, and 441,141 are referred to.

Abstract: 894,188. Batteries. SERVEL Inc. Oct. 24, 1958 [Oct. 28, 1957], No. 34067/58. Class 53. An alkaline primary cell which is normally airtight but which allows gas under excessive pressure to escape comprises two steel cups 1, 2 having paper or other absorbent material 11 between them. Within the inner cup is the depolarizer 3, barrier disc 4, an absorbent separator 5 and the zinc anode 6. The depolarizer may consist of an oxide of mercury, silver, or copper, mixed with graphite, and the disc 4 may be made of parchment paper, synthetic resin, compressed magnesium oxide or silicate. An insulating cylinder 12 prevents internal shortcircuiting. Connection to the anode is made by the head 7a of a rivet 7 which passes through sealing discs 8a, 8b, cup 1, an insulating disc 9 and a metal plate 10 upon which the end of the rivet 7 is upset. The separator 5 may consist of several pads of fibrous cellulose in which a solution of sodium, potassium or lithium hydroxide is absorbed. Oxide of zinc or aluminium may be included to inhibit attack on the zinc when the cell is not in use. The anode consists of compressed amalgamated zinc powder. The discs 8a, 8b form a closure for the cup 2, the disc 8b being of a resilient material, for example neoprene, polyethylene or vulcanized fibre, and the disc 8a being of a semi-rigid material, for example a phenolic or melamine resin. Pressure is maintained between the discs and the rim of the cup 2 by the open end of the cup 1 which is crimped over the bottom of cup 2. Excessive gas pressure within the cell forces the disc 8b away from the rim of the cup 2, and gas escapes through the material 11 and between the cup 2 and the crimped end of cup 1.

Title: Improved method of recovering metal values from solutions
Inventor: MACKIW VLADIMIR NICOLAUS
IPC: C22B3/44
Filed: 1953-12-09
Abstract: Nickel, cobalt and copper are precipitated from ammoniated solutions in which they are present as soluble compounds by reacting the solutions with a reducing gas such as hydrogen in a reaction vessel under superatmospheric pressure, e.g. above 100 lbs./sq. inch, and superatmospheric temperature, e.g. above 200 DEG  F., a nucleating agent being present in the solutions to initiate and accelerate the reducing reaction.  A solution being subjected to reduction may contain ammonium sulphate and preferably sufficient ammonia is maintained in the solution during reduction to provide at least 2 mols of ammonia per gram-atom of metal to be reduced.  Nuclei produced by such a reduction may be added to a further solution which is then reduced without addition of nucleating agent.  Thus successive solutions may be added to the reaction vessel containing reduced metal nuclei until metal begins to plate on the walls of the reaction vessel.  The adhering metal is dissolved off and the process repeated.  Among the nucleating agents which can be used are those which act as reducing agents such as compounds including a polyvalent metallic ion in its lowest state of oxidation, e.g. a ferrous compound which may be used in an amount greater than 0.1 grams per litre.  A mixture of ferrous sulphate and ferrous ammonium sulphate may be used.  Other agents which may be used are carbonate, hydroxides, sulphides and finely divided carbon.
